i haven't had that but I did have a guest angry at me that i wouldn't GIVE her the candy so she could "donate" it to the food bank. This guest is always trying to get a "deal" and i'm pretty positive she wasn't going to donate it. She was very upset that we would not help out our community by giving her this candy so i politely explained to her that we do donate to the food bank weekly and made sure i smiled sweetly and thanked her to being concerned with our community and wanting to help. She huffed and puffed and left without buying anything! Gave me a good laugh!
